This invention relates generally to brushes and more. particularly to holders therefor by which the brush bristles can be protected against contamination during such periods as the brush is not in use.

An object of the invention is to provide a brush particularly adapted, although not necessarily for use in the art of make up asl practiced by theatre and cinema artists, and structurally characterizedby extremely simple and highly efficient means which is manually operable by a positive mechanical operation to expose the brush bristles for use or-conceal the bristles in a prac' tically sealed housing when not in use, so as to l5 adequately protect the bristles from such contacts or exposure as might contaminate the bristles, all to the end of promoting sanitation and precluding premature discarding of the brush because of an unclean condition thereof.

Another object of the invention is to provide a sanitary brush wherein the brush bristles are adapted to be enclosed in housing sections which are rockably mounted on the handle of the brush for positive actuation to expose or conceal the bristles by a cam common to the housing sections, and manually actuatable in an axial direction relative to the handle through the medium of a plunger in the-handle, to which the cam is fixed.

` A further object of the invention is to provide a sanitary brush of the above described character wherein the various parts thereof can be easily and quickly assembled to form the complete brush without the use of extraneous fastening means, and in a manner for the parts to be selfmaintained in proper working relationship.

With these and other objects in view, the invention resides in the combinations, arrangements and functional relationships of elements as set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a view of the brush in side elevation;

Figure 2 is a longitudinal sectional view taken on the line 2-2 of Figure l, and showing the brush bristles enclosed by the housing;

Figure 3 is' a view similar to Figure 2, and illustrating the bristles exposed for use;

Figures 4 and 5 are enlarged transverse sectional views taken on the lines 4--4 and 5--5 of Figure 2;

Figure 6 is a fragmentary longitudinal sectional view ofthe head portion of the brush handle;

Figure 'l is a'perspective view of one of a plurality of identical housing sections which are coactable to form the bristle enclosing housing;

Figure 8 is a fragmentary view in side elevation, of a second form of sanitary brush embody- 5 ing this invention;

Figure 9 is a view in side elevation of the second form of sanitarybrush, at a right angle to Figure 8.

Referring specifically to the drawing, and par- 10 ticularly to Figures 1 to '1, inclusive, this form of the invention comprises a-handle I0 composed of a tubular shank II of uniform diameter having an enlarged cylindrical portion or head I2 at one end, the bore I3 of which head is co-axially re- 15 lated to, and somewhat larger in diameter than the bore I4 of the shank II.

At diametrically opposed points, the head I2 is provided with openings I5 preferably of generally A rectangular outline and extending through the 20 annular -wall 'I6 thereof. The internal surface of the wall I6 is provided with longitudinally extending grooves I'I extending from the openings I5 to the free end of the head.

A brushing element I8 having bristles I9 is 25 fixed to one end of an actuating rod 20 slidable freely in the bore I4 of the shank II and having a force t at its other end in the base 2I of a cup shaped cap 22, the bore 23 of which telescopically receives the adjacent end of the shank. 30

Adjacent the brushing element I8 and fixed to the rod 20 so as to work in the bore I3 of the head I2, is an actuator in the form of a cam 24 for the two identical sections 25 of a streamlined housing 26 which is adapted to enclose or expose 55 the brushing element I8 according as the latter occupies the retracted position shown in Figure 2 or the advanced position shown in Figure 3.

Eachl housing section 25 is provided with a longitudinal extension 2l terminating in a pivot lug 40 or trunnion 28 which is generally rectangular in outline to freely t in one of the openings I5, whereas the extension 2l'` is freely received in one of the grooves Il, all to the .end of rockably mounting the housing section on the handle. 45

It will be noted that shoulders 29 and 3IJ on each housing section confine the latter against displacement axially of the handle, and that the cam 24 is of. a generally. semi-spherical shape to ride against the internal cam surfaces 3I of the 50 housing sections for co-action with such surfaces in positively rocking the sections to their closed or opened positions according as the cam is actuated to occupy the advanced or retracted position shown, respectively, in Figures 2 and 3. 55

In the closed position of the housing sections, the canill tightly engages the cam surfaces Ii at a point substantially opposite the lugs 28, and exerts sumcient pressure against the surfaces to maintain the confronting flat faces $2 oi.' the sections in sealing contact with each other so as to adequately protect the brushing element from contamination.

In the operation of the invention, the brushing element il is exposed for use by pushing against the cap 22 so as toacause the cam 24 to ride upon the surfaces ll' and positively spread the tip ends of the housing sections 25 only suiilciently for the brushing element to pass freely therebetween.

Upon reversely moving the cap 22 relative to the handle i0, the reverse movement of the housing sections will be eifected until the brushing element is fully retracted and sealed in the housing, this position of the element being definitely limited by co-action of a shoulder 32 pn the rod 2li with a shoulder 22 in the head i2.

To assemble the various parts of the device, the two housing sections 25 are applied to the handle i as shown in Figure 3, following which the rod 20 is inserted between the sections into the handle il and then forced into the cap 22.

VThe cam 24 now positively prevents displacement of the lugs 2l from the openings i5, so that the parts will be maintained assembled in their proper working relationship.

Reference will now be had to Figures 8 and 9, wherein is disclosed a second form of rockable mounting for the housing sections 25a in the head i2a of the handle lila. The head i2a is provided with obliquely disposedv slots Il at diametrically opposed points and extending from the periphery of the head to terminate in iaterally offset bearings 35 for trunnions 36 on extensions 31 of the housing sections, which exten. sions work in slots 38 of the head I2a. When the housing sections are applied to the head, and the rod 2li is assembled therewith, the cam 2l will co-act with the sections in the mannerl previously described, to positively prevent displace ment of the trunnions 35 from the bearings so as to rockably mount the sections on the head to function in a manner identical to that described for the heads 25.
